Here is Custom Galatic Marine that I made a few months ago. Its a pretty good attempt for my first custom.

About this creation

Here is a higher view of the custom, sorry about the glare.

Heres a back view, as most of you would have guessed I used a Imperial Snowtrooper's helmat and pack.

Here is a front view, if you look closely you can see that the chest part is just a decal. I took a picture of the real torso and cropped & edited it in PS, I might redo that part and make most of the decal the same colour as the torso part as it should be.

I will update the page when the other decal is created, in this one which I didn't include was some Kama armour that is the colour of paint I used Mechrite Red.

4 the body did you draw it on paper then stick it on?????cos i did and it worked.

I accuctally Photographed a Snow Troopers chest part and edited it in PHOTOSHOP (Made certain parts for pronounced and added a few extra bits, the i printed it on a standed piece of paper (A4), then just glued it on. Pretty simply.
If you dont have access to PHOTOSHOP then you can download Paint.net or contact me if you want something done e.g.Image editing/effects, custom decals. Stuff like that.
